Abstract: A method for producing an extruded polystyrene foam in which when a foamable melted product, obtained by heat-melting a styrene resin composition and adding a foaming agent thereto in an extruder provided with a die slit section having an opening a (mm) in the thickness direction, is extrusion-foamed through the die slit section into a low pressure zone to form a plate-shaped foam, thereby obtaining an extruded polystyrene foam having a density of 20 kg/m3 or more and 45 kg/m3 or less, a closed cell ratio of 90% or more, and a thickness A (mm) of 10 mm or more and 150 mm or less, a foaming agent containing hydrofluoroolefin and other organic foaming agent is used, a thickness extension ratio A/a of an opening a in the thickness direction of the die slit section and a thickness A of the extruded polystyrene foam is adjusted to 18 or less, and a foamable melted product, just before the extrusion from the die slit section, is pressurized to 4.5 MPa or more and 10.0 MPa or less.

Abstract: An extruded polystyrene foam is produced by performing extrusion-foaming with a styrenic resin, a flame retardant composition, and a foaming agent. The flame retardant composition includes a brominated styrene-butadiene polymer, a stabilizer, and a styrenic resin; the brominated styrene-butadiene polymer is contained in an amount of 30 to 80 wt % where the total weight of the flame retardant composition is 100 wt %; and the flame retardant composition has a TGA 5 wt % reduction temperature of 255 to 270° C. The extruded polystyrene foam has excellent thermal stability, excellent flame retardancy, and an excellent appearance.
